Mercury Impeller Body Assembly (8M0139984)

Mercury Impeller Body Assembly (8M0139984)

The Mercury Impeller Housing Assembly (8M0139984) is a critical cooling component in Mercury marine engines, located at the heart of the water pump system, ensuring the impeller operates correctly and efficiently. In Mercury engines, the impeller housing supports the proper direction of water flow within the pump and maintains stable pressure. A robust housing with precise tolerances directly contributes to maintaining the engine's ideal operating temperature.

This complete impeller housing, coded 8M0139984, is manufactured to withstand the harsh conditions of the marine environment, including saltwater, sand, and constant pressure. Wear or deformation on the housing surface can reduce the impeller's efficiency, leading to insufficient water circulation and overheating. Therefore, it is crucial to inspect the housing along with the impeller during water pump maintenance and replace it if necessary.
